Electric power supply system for motor vehicle

A power supply system for a motor vehicle includes a battery (2) of high voltage for a load system (3) rated at 48 V and a high-voltage generator (1) for charging the battery. Loads rated at high voltage is supplied with electric power directly from the battery. A power MOS IC element (41) connected...

More Information
Summary:A power supply system for a motor vehicle includes a battery (2) of high voltage for a load system (3) rated at 48 V and a high-voltage generator (1) for charging the battery. Loads rated at high voltage is supplied with electric power directly from the battery. A power MOS IC element (41) connected in parallel with the battery is controlled in respect to the duty factor for producing at the output terminal thereof a low voltage of 24 V or 12 V on an average, wherein low-voltage loads (5, 6) are controlled by the low output voltage.
